• Inputting cheat codes - hidden keyboard input

  - by Fibericon

  Okay, here's what I want to do - when the player is at the main menu, I want them to be able to type in cheat codes. That's the only place I want it to work. I don't want to give them a text box to type into. Rather, I want them to simply type in a word (let's say "cheat", just for simplicity sake) that activates the cheat code. I only need to capture keyboard input when the window is in focus. What can I do to accomplish this?

• How can I track scrolling in a Google Analytics custom report?

  - by SnowboardBruin

  I want to track scrolling on my website since it's a long page (rather than multiple pages). I saw several different methods, with and without an underscore for trackEvent, with and without spaces between commas <script> ... ... ... ga('create', 'UA-45440410-1', 'example.com'); ga('send', 'pageview'); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 100, true]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 75, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 50, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 25, false]); </script> It takes a day for counts to load with Google Analytics, otherwise I would just tweak and test right now.

• Looking for menu-driven coding platforms

  - by user2634047

  Can anyone point me to an application development environment that uses menu-driven coding? This would mean where commands, variable names, etc. are not keyed in, but rather are selected from a menu of context-specific options. For example, the user selects an If...then command from a menu of commands, and is then presented with a menu of variables to choose from for the the 'if' conditions(s) (or creates new variable(s) on the fly via the menu), and is then presented with a menu of applicable functions that are applicable to the selected variable (e.g., val()), and so on until the If...then statement has been fully coded. The idea is that the user never types any portion of the code, but selects all code elements from a menu, or defines them on the fly via the menu. Thanks.

• Refactoring While Programming

  - by Kirby

  When posed with a problem, particularly when it is complicated in nature, I try to take some time to think about the approach I am going to take to solve the problem. Despite this, what often happens is, as I am programming the solution, I start to think of details of the problem that I missed, and I adjust the code accordingly. What results is a mess of code that needs to be refactored. I want to "refactor as I go," but while it sounds easy enough to do, I have a really hard time doing it. When the detail that I missed is small, it is tempting to make a small update to my design, rather than erase what I've already written and write it the way it is supposed to be. It sounds like a question with an obvious answer, but are there any techniques to use to better "refactor as you go"? I know that this is a good principle, but I fail with it time and time again.

• Are Intel HD 4000 graphics supported on Ubuntu 10.04 LTS?

  - by user1118764

  I have an intel Core i7-3700 system with Intel HD 4000 integrated graphics with a dual monitor setup (1 connected via VGA, the other via DVI) on Ubuntu 10.04 LTS 64bit. I'm trying to get my monitors correctly detected. Right now, in only 1 unknown monitor is detected with a max resolution of 1280x1024, which is lower than my main monitor connected to DVI. Also, the desktop is mirrored rather than extended. I've previously managed to get a Core i5-2400 system with Intel HD 3000 integrated graphics with the same dual monitor setup and Ubuntu 10.04 LTS 64bit to work using the glasen ppa drivers, but this time, after installing them following the instructions How do I install the Intel HD 3000 video driver? but it doesn't seem to work. Does the Intel HD 4000 require a different driver from the 3000? If so, where can I get it?

• Algorithm development in jobs

  - by dbeacham

  I have a mathematics background but also consider career in some form of software development. In particular I'm interested in finding out what sort of industries are most likely to have more algorithm development/mathematical and logical problem solving slant rather than pure application development etc. Obviously, I'm assuming that some subset of the canonical data structures and associated algorithms (trees, lists, hash tables, sets, maps with search, insert, traversals etc.) are mostly going to be present in software development. However, where am I more likely to encounter problems of more discrete maths nature (combinatorial, graph theory, sets, strings, ...) explicitly or more likely in disguise. Any pointers much appreciated (including possible open source projects that I could use for my further search for applications and also possibly contribute to).

• what else except web development is a good choice for freelancing? [closed]

  - by Sali

  I'm looking for a technology that when I learn I can build useful things that brings money by selling what I have built. I tried web development but Ifound that there are many things that I have to learn: html, css, javascript,ajax,jquery ,etc. I need to focus on one thing and learning it from scratch and continue learning if there is any update in that technology rather than learning new things in css and javascript and the server side language. I want to focus! However, I'm not sure what is going on in the future of technology and I need to learn something for freelancing. could you tell what is the thing thatis popular and will bring me money as good as web development?

• Going from webforms, VS 2008, 3.5 framework to the "next level" based on my goals

  - by Caveatrob

  I've got a few choices to make as I develop some business websites that will run for the next two to three years. Currently I run ASP.NET 3.5 with Visual Studio 2008. I do my development rather crudely in WebForms because that's what I learned and am most productive with. I don't use Membership or any other frameworks in my projects. I use a simple class that maintains a few session keys for each user based on basic database tables for users and roles. (I have about 3,000 users). So far I've kept the data simple, using ADO.NET against SQL Server and a data access class (Circa 2000, I know) to build my sites. My questions are as follows: Under what conditions would I be better off moving to MVC? Under what conditions would I find LINQ and ORM a better way to go than standard ADO.NET? Would I benefit, in my current state of development, from going from Studio 2008 to Studio 2010?

• Is there a word or description for this type of query?

  - by Nick

  We have the requirement to find a result in a collection of records based on a prioritised set of search criteria against a relational db (I'm talking indexed field matching here rather than text search). The way we are thinking about designing the query is to begin with a highly refined and specific set of criteria. If there are no results for this initial query we want to progressively reduce the criteria one by one in order of reducing priority, querying each time such a less specific set of criteria until we find a result we can accept. Alternatively, we have considered starting with a smaller set of criteria and increasing until we have reduced number of results down to the last set. What I would like to know is if an existing term to describe this type of query exists? So that we can look to model our own on existing patterns and use best practice.

• What is the difference between all-static-methods and applying a singleton pattern?

  - by shahensha

  I am making a database to store information about the users of my website (I am using stuts2 and hence Java EE technology). For the database I'll be making a DBManager. Should I apply singleton pattern here or rather make all it's methods static? I will be using this DBManager for basic things like adding, deleting and updating User profiles. Along with it, I'll use for all other querying purposes, for instance to find out whether a username already exists and to get all users for administrative purposes and stuff like that. My questions What is the benefit of singleton pattern? Which thing is most apt here? All static methods or a singleton pattern? Please compare both of them. P.S. The database is bigger than this. Here I am talking only about the tables which I'll be using for storing User Information.

• Possible / How to render to multiple back buffers, using one as a shader resource when rendering to the other, and vice versa?

  - by Raptormeat

  I'm making a game in Direct3D10. For several of my rendering passes, I need to change the behavior of the pass depending on what is already rendered on the back buffer. (For example, I'd like to do some custom blending- when the destination color is dark, do one thing; when it is light, do another). It looks like I'll need to create multiple render targets and render back and forth between them. What's the best way to do this? Create my own render textures, use them, and then copy the final result into the back buffer. Create multiple back buffers, render between them, and then present the last one that was rendered to. Create one render texture, and one back buffer, render between them, and just ensure that the back buffer is the final target rendered to I'm not sure which of these is possible, and if there are any performance issues that aren't obvious. Clearly my preference would be to have 2 rather than 3 default render targets, if possible.

• How can I make Banshee re-encode FLAC to Ogg Vorbis when copying to my player?

  - by Michael E

  I have most of my music in FLAC on my large storage device, and would like to automatically re-encode it in Ogg Vorbis when copying it to my portable audio player (Sansa Fuze v2). I have set my Fuze to MTP mode and told Banshee to encode to Ogg Vorbis with quality 4 in the Device Properties dialog for the Fuze (I would use MSC mode, but don't have an encoding option in the device properties when I do that). However, when I copy music to the device, either by dragging it from the music library or by syncing a playlist, the full FLAC files are copied rather than transcoded and written as Oggs. How can I get my Banshee setup re-encoding the audio? If StackExchange supported bonus points, I'd give bonus points for a solution that only re-encoded music that was already losslessly encoded, but I don't think that's possible.

• Will Ubuntu be releasing an update for Cedar Trail Processors?

  - by Alan

  There is a file available on the Intel web site with the file name "cdv-gfx-drivers-1.0.1_bee.tar.bz2" and a date of July 6, 2012. It can be found by searching the Intel Download Center for the filename or the string "Linux* PowerVR Graphics/Media Drivers". The download page links to the file, release notes and a link, Enabling hardware accelerated playback that takes one to a page containing links to two pdf documents titled "Enabling Hardware Accelerated Playback for Intel® AtomTM Processor N2000/D2000 Series", one for Ubuntu and one for Fedora. The instruction and release notes speak to working with kernel 3.1.0 and since I do not feel I have the skills, knowledge or training to do anything else but, follow the instructions to the "T", I am very reluctant to try anything on my freshly updated 3.2.0 kernel. I would much rather use a Ubuntu supported kernel that applies these drivers and doesn't break anything in the process. Is it a case where this is so new that Canonical has not yet included these drivers but, soon will do so?

• Reputable web host in mainland China? [closed]

  - by darren

  Possible Duplicate: How to find web hosting that meets my requirements? We currently have a rather poorly set up Windows 2003 box with little to no support based in Shanghai; with no control panel/mail server. I am told for legal/business reasons the host must be based in the same location as the company for the website; but this could well be misinformation. Are there any well-known, quality hosts in China that offer reliable English-speaking support? We did consider GoDaddy on the west coast of America, but were informed of the risk of the site being shut down without any notice. We don't have any technically-minded contacts out there to advise, and hoping that someone will have some more experience in this department. Thank you.

• How to completely uninstall LXDE (12.04)?

  - by Jeremy Lunsford

  I'm trying to remove LXDE from my 12.04 system. I've tried running the following commands (as root from a terminal): apt-get remove lxde apt-get purge lxde apt-get autoremove I've also tried a rather lengthy command that was linked to from another question. However, when I log in, LXDE is still presented as an environment choice, and it still functions perfectly well, as if I've done nothing. I ran the above commands again, but got the following message: package . . . is not installed, so not removed. So, where do I go from here, short of re-installing Ubuntu and all my programs?

• I need a backend system that is integrated with web services, is there an open source solution?

  - by Jarom

  I'm basically familiar with what I need in order to setup web services to talk with a centralized db, but if I don't have to go through and do all the work, I'd rather not. Is there an open source solution that would allow me to easily integrate web services for data transfer to a central db? I want to make a site that is powered by a db that can also be accessed by other things like mobile apps for example. What are the steps involved in setting up such a site? Any help is appreciated! I could use all the help I can get!

• How to start to gain experience of managing a project

  - by Tim

  There are some job requirements of project management experience for a programmer, such as: the candidate has to have some experience managing a project, not necessarily with subordinates, but rather having worked on a project all the way from design down to test. I was wondering what "subordinates" mean here? if there are some books, webpages or elsewhere with both general guideline and simple practical sample projects to help one get some basics about the whole process of a project. I am particularly interested in projects for both Linux and Windows, in C, C++, Python, Java. I am considering to start by playing on my own, not eager to find a company yet. My major was not CS, so I might lack the basics.

• 3 SQL Join Concepts to Help You Choose the Right Join

  What do SQL joins and the "teach a man to fish" Chinese proverb have in common? SQL joins, like regular expressions, are one of those commonplace programming tasks in which true success is entirely dependent upon your ability to conceptualize the outcome. Fail to do so and you'll likely wind up spending a few hours in a frustrating round of trial and error. Like regular expressions, the proliferation of online examples has actually contributed to the frustration, providing the equivalent of a day's worth of fish rather than the proverbial fishing pool.

• Design Patterns for SSIS Performance (Presentation)

  Here are the slides from my session (Design patterns for SSIS Performance) presented at SQLBits VI in London last Friday. Slides - Design Patterns for SSIS Performance - Darren Green.pptx (86KB) It was an interesting session, with some very kind feedback, especially considering I woke up on Friday without a voice. The remnants of a near fatal case on man flu rather than any overindulgence the night before I assure you. With much coughing, I tried to turn the off the radio mike during the worst, and an interesting vocal range, we got through it and it seemed to be well received. Thanks to all those who attended.

• how to bind super+s to indicator applete complete? - gnome classic

  - by rrosa

  i use gnome classic, i'm not a mouse fan. when i get an email while i'm writing code, i i would super+s to get to the indicator-applet-complete and read it. also to write emails, or check unread instant messages. upgrading from 12.04 to 14.04 made super+s bind to applications menu rather than the indicator applet complete. i removed the binding from the applications using dconf-editor, navigating to: org-gnome-desktop-wm-keybindings and disabling (['disabled']) the panel-main-menu key. now, how do i bind super+s to the indicator applet complete? it seems to be some how binded, since if if press super+s and then move the cursor over the applet it'll open the drop down menus (and it won't if i hover without pressing super+s) but i don't want to have to use the mouse...

• How do I change the cursor and its size?

  - by Thomas Le Feuvre

  I have recently created an Ubuntu 12.04 partition on my Windows 7 laptop. When installing it, I switched to "high contrast" mode, which has rather large cursors (by large I mean about twice as large and thick as they should normally are). Now I have successfully installed the partition, the large cursors have stuck around even after exiting this high contrast mode, but only when I am hovering over stuff e.g. hovering over text inputs, links, and when resizing windows. All of these cursors are too large. They cursor is only normally sized when the computer should be displaying the normal mouse pointer. Does anyone know how I might go about fixing this?

• Trust External Surround Soundcard SC-5500p not working

  - by Ederico

  I got the following external sound card to make some awesome noise with my speaker set. It should be plug and play, but it so happens that when I plug it in and hook everything up, there's no sound at all. The speaker set I have works if I plug it in the laptop directly (or rather, if I plug the front speakers cable as I can't plug anything else). http://www.trust.com/products/product.aspx?artnr=14134 Would anyone know how I can workaround this problem and make full use of this external sound card on my Ubuntu 12.04 system?

• BIT of a Problem

  The BIT data type is an awkward fit for a SQL database. It doesn't have just two values, and it can do unexpected things in expressions. What is worse, it is a flag rather than a predicate, and so its overuse, along with bit masks, is a prime candidate for being listed as a 'SQL Code Smell'. Joe Celko makes the case.

• Auto-provisioning hosting via API

  - by user101289

  I've built a sort of 'software as a service' website package for a specific industry. What I am looking to do is create a payment gateway that allows users to subscribe-- and once the subscription is active, it would auto-provision a web hosting plan for them (a shared account on a server, probably in a chroot'd environment so each user would be insulated from others). Ideally it would auto-install a CMS as well. Tons of web hosts provide a simple reseller plan where I could manually create all the users' hosting accounts-- but so far none that I've found allow you to do this via API. Is there a way to do this short of writing custom shell scripts on something like an EC2 platform? I'd prefer to leave all the server maintenance in the hands of dedicated support staff rather than having to manually handle updates, backups, etc. Thanks for any tips.

• Starting application in same window with XFCE4 Terminal and i3

  - by Luke

  Since recently I'm enjoying the i3 tiled window manager. I did install the XFCE4 Terminal since it gives greater control over my terminal look and feel however but I have noticed an issue with starting GUI based applications. When I execute a GUI based application I want it take over the current terminal window. To do this I use exec, as in: exec eclipse This will open a new window and leave the terminal I started the application in open as well. In normal circumstances this is not much of a problem since I can easily do an Alt-W on the GUI app's window. However, for some applications, like a file manager, it is necessary to open in the same window. How can I make GUI application open in the same window rather than opening a new one?
